ANNEALING SPIDER Y Filed Sept. 23, 1955 ATTORNEYS ANNEALING SPIDER JohnP. King, North Haven, Conn., assignor to The Alfred B. King Company,North Haven, Conn., a corporation of Connecticut Appiication September23, 1955, Serial No. 536,079

3 Claims. (Cl. 263-47) This invention relates to an annealing spider orarbor for supporting coils of wire or rod during annealing or similaroperations or in transporting the coils from one place to another.

In a device for this purpose it is desirable to provide an arbor orspider which will be sulficiently strong for supporting a number ofcoils of rod or wire so that they may be handled expeditiously by ahoist or like mechanism and which will be of such structure that it willwithstand the rather severe usage to which such a device may be put andalso stand the heat to which the coils may be subjected without warpingor losing its shape. Also it is desirable to so construct the spiderthat there will be a free flow of hot gases around the materialsupported upon it so that the coils will be evenly and efficientlyheated. At the same time the coils should be so supported that they willbe maintained in circular form and not be distorted from their roundshape.

It is also contemplated by the present invention to provide a relativelyshort stacking spider which is so constructed that one may be supportedon top of another with a coupling pipe between the two spiders to holdthem in alignment.

As illustrated, the spider or arbor comprises a bottom plate having aloading stem or core rising therefrom, this core being formed of aplurality of formed metal sections of substantially V-shaped form, theadjacent edges of these sections being joined together to form a hollowribbed cylinder with the vertices of the sections extending outwardlyfrom the seams between the sections. This in effect provides areinforced core of hollow generally cylindrical form by providing apoint or line contact with the coils when placed upon the core. Such aconstruction forms a veryrigid core which will withstand the stresses towhich it is necessarily subjected and at the same time provides aminimum area of contact between the core and the coils, keeping thecoils round and at the same time preventing sticking of the coils to thecore.

One object of the invention is to provide an annealing arbor or spiderof improved construction and design.

A further object of the invention is to provide an annealing arbor orspider which will be so constructed as to maintain at a minimum themetal-to-metal contact between the spider and the coils and at the sametime provide a rigid construction which will not be likely to be warpedor distorted when in use.

Still another object of the invention is to provide an annealing arboror spider of the character described which will have provision for freecirculation of the hot gases through the various elements of the spideritself and also around the coils so that the latter may be evenly andefficiently heated.

Still another object of the invention is to provide an arbor or spiderconstructed of plate-like sections of substantially V-shaped form incross section and so join the sections together that they will beproperly braced States Patent Patented May 13, 1958 Fig. 1 is a sideelevational view of an annealing arbor or spider embodying my invention;

Fig. 5 is a view partly in section and partly in elevation of thecoupling member employed for joining one spider to another when one issuperposed upon the other.

To illustrate one embodiment of my invention I have shown in the drawingan annealing arbor or spider comprising a base plate 10 which in thisinstance is of substantially circular form, this plate being secured tothe lower end of a core designated generally by the numeral 11, thiscore being hollow and of generally cylindrical form and of aconstruction to be described hereinafter. the base plate 10 is providedwith an opening 12 (Fig. 3), this opening permitting the hot gases topass upwardly through the hollow interior of the core 11 and thediameter of the opening being such that it is substantiallycircumscribed within the sections of the core.

As shown more especially in Fig. 4, the core or stem 11 is formed of aplurality of substantially V-shaped sections 13, these sections beingconstructed of metal plate formed as shown so that they aresubstantially of V shape in cross section. The vertices or ridges 14 ofthese members are directed outwardly and at their inner edges onesection abuts the inner edge of an adjacent section, as shown at 15, andthese edges are welded together, thus forming a reinforced ribbed orrigid generally cylindrical structure of hollow form.

It may be noted that with the vertices or ribs of the sectionsprojecting outwardly, the coils when placed upon the arbor will abutthese ridges and only contact the core at these points. There will,therefore, be a minimum of contact between the coils and the exteriorsurface of the core although the coils will be maintained in their roundshape as a sufficient number of sections will be provided for thispurpose, eight as shown in the drawings.

This core formed as explained above is placed upon the base plate 10 andsecured thereto by welding or the like. As shown in the top plan view ofFig. 2, the base plate is also provided with a plurality of throughopenings 16 to permit circulation of gases therethrough and around thecoils, all of these openingsbeing disposed between adjacent sections 13.Thus the hot gases may rise through the openings 16 on the outside ofthe core as well as through the opening 12 upon the inside. It will alsobe understood that the base. plate 10 is of larger diameter than theoutside diameter of the core so that the coils of wire indicated at 17in Fig. 1 will rest upon this projecting portion of the base plate.

A cover plate 18 may be provided upon the core,'this plate being ofsubstantially the same shape and size as the shape and size of the crosssection of the core itself so that the sections will be braced at thetop and held rigidly in place, this cover plate also being welded to thesections of the core. This plate'is provided with an opening 19 topermit exit of the (gases passing through the center of the core.

3 It is noted that the diameter of the opening 19 is less than thedistance across the interior or" the core between opposite edges thereofso that the portion of the cover plate around the opening 19 willoverhang the interior of the core to provide for the lifting of thearbor by crane books or the like inserted through the opening.

Secured within the core, as shown more especially in Figs. 3 and 4, is areceptacle or socket member comprising ahollow cylinder body 20 and endflanges 21 and 22, the periphery of these flanges being secured bywelding or the like to the inner edges 15 of the sections 13 so as tosecure this member in place and also serve to some extent to brace thesections 13.

A coupling member,-shown in Fig. 5, consists of a pipe or stem 23 towhich .is-Vsecured an-enlarged body portion 24. These members are.hollow and the top of the body portion is provided with van opening25so there will be free circulation of gases ,upwardly through thecoupling member. As shown in dotted lines in Fig. 3, the coupling membermay be .placed uponthe-cover plate 18 with the I stem 23extending-downwardly through the opening 19 and fitting snugly withinthe body portion 2% of the receptacle while the body member 24 restsupon the plate 18.

When it is desired tostack a second arbor upon the first, the couplingmember is put into place,-as shown in Fig. 3, and the second arborlowered upon the first. The body portion 240i the coupling member which,as shown, is tapered upwardly and inwardly will be received in theopening 12 in the .base plateof the upper arbor and will hold the two inalignment. It will be noted that when two or more of the arbors arestacked one upon the other in this manner, a continuousopening isprovided therethrough by reason of the opening through the couplingmembers and the hollow interiors of the cores 11.

By the above construction there is provided an arbor which may beeconomically made and which at the sam time will be of rigid and strongconstruction to withstand the stresses to whichit may be subjected. Atthe same timea minimum area-of contact is provided between the arbor andthe coils .17 due to the fact that thereis substantially a .linecontactbetween the vertices 14 and the coils andat the same time the verticeswill contact the coils to maintain-their round shape. Also thereisprovided a freecirculationof hot gases through the interior of the corewithin the hollow sections 13 and also around the coils on theoutsideof.the core by reason of the openings 16.

While I have shown and described one embodiment of my invention, it willhe understood that it is not to be limited'to all of the details shown,but is capable of modification and variation within the spiritof theinvention and within the scope of the claims.
